由鋼波紋涵管外圓(yuan)弧(hu)波紋(wen)膜(mo)片(pian)對(dui)壓力(li)有(you)線性特性，所以得到的外圓(yuan)弧(hu)波紋(wen)末膜(mo)片(pian)的計算結果，還能用于(yu)(yu)膜(mo)片(pian)受力(li)變(bian)(bian)形(xing)較(jiao)大(da)的情況。由此而擬合出的設計公式能適(shi)應于(yu)(yu)變(bian)(bian)形(xing)較(jiao)大(da)的情況。

鋼波紋涵管的外圓弧波紋末膜片的計算如何運行？

從儀表(biao)的結(jie)構(gou)的特點(dian)來考(kao)慮，有些鋼波紋(wen)(wen)涵管的無外(wai)(wai)波紋(wen)(wen)。鋼波紋(wen)(wen)涵管可分為(wei)有外(wai)(wai)波紋(wen)(wen)和無外(wai)(wai)波紋(wen)(wen)兩種。對于不(bu)同的鋼波紋(wen)(wen)涵管的計算也是不(bu)一樣的。

實踐(jian)證(zheng)實，用金(jin)屬波(bo)紋(wen)管(guan)(guan)涵(han)代替金(jin)屬筋混凝土進(jin)行(xing)(xing)涵(han)洞(dong)施(shi)工(gong)，不(bu)管(guan)(guan)從(cong)施(shi)工(gong)周期、施(shi)工(gong)造價、環(huan)保意(yi)義等(deng)方(fang)面都有(you)其不(bu)可相比的(de)優勝性，且用金(jin)屬波(bo)紋(wen)管(guan)(guan)涵(han)進(jin)行(xing)(xing)涵(han)洞(dong)施(shi)工(gong)，可大大進(jin)步道(dao)路行(xing)(xing)車的(de)恬靜度與安全性，避免(mian)道(dao)路中涵(han)洞(dong)的(de)“錯臺跳車”現形，有(you)利于解決(jue)西北地區(qu)嚴寒霜凍對砼管(guan)(guan)涵(han)結(jie)構的(de)破壞題(ti)目 。

跟著鋼波紋涵管在世界各地(di)的(de)安裝使用(yong)(yong)，證(zheng)實(shi)了此(ci)種結構(gou)在各種使用(yong)(yong)情況(kuang)下的(de)通用(yong)(yong)性。在我(wo)國改革(ge)開放后，深圳及大同煤(mei)礦開始從國外入(ru)口(kou)成品波(bo)紋(wen)管涵進(jin)行涵洞施(shi)工。之后，上(shang)海(hai)市公路治理處、上(shang)海(hai)市政(zheng)工程設計研(yan)究(jiu)院(yuan)、上(shang)海(hai)同濟(ji)大學對金屬(shu)波(bo)紋(wen)管涵進(jin)行了動(dong)、靜載試(shi)驗，結果表明(ming)能知足設計使用(yong)(yong)要(yao)求，填補(bu)了海(hai)內的(de)空缺(que)，且迅速得(de)到推廣應(ying)用(yong)(yong)。幕墻(qiang)一貫反應(ying)用(yong)(yong)于我(wo)國各地(di)公路舉措措施(shi)建設當(dang)中。金屬(shu)波(bo)紋(wen)管涵投入(ru)到了青海(hai)公路施(shi)工當(dang)中，三年(nian)的(de)實(shi)踐證(zheng)實(shi)，金屬(shu)波(bo)紋(wen)管涵在北方(fang)嚴寒地(di)區完全符(fu)合公路建設當(dang)中的(de)涵洞施(shi)工要(yao)求。  

公路(lu)工(gong)(gong)(gong)程的(de)涵(han)(han)洞(dong)(dong)一般采(cai)用金(jin)屬(shu)筋混(hun)凝(ning)土(tu)(tu)(tu)制作(zuo)。現采(cai)用金(jin)屬(shu)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)代替(ti)(ti)金(jin)屬(shu)筋混(hun)凝(ning)土(tu)(tu)(tu)進行涵(han)(han)洞(dong)(dong)施(shi)(shi)工(gong)(gong)(gong)在(zai)海內時一項新技(ji)術，金(jin)屬(shu)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)以其機能不亂、安裝利便、有(you)利環保、造價低等(deng)長(chang)處(chu)迅速在(zai)公路(lu)施(shi)(shi)工(gong)(gong)(gong)中代替(ti)(ti)了(le)金(jin)屬(shu)筋混(hun)凝(ning)土(tu)(tu)(tu)施(shi)(shi)工(gong)(gong)(gong)的(de)涵(han)(han)洞(dong)(dong)，發展遠景非常廣闊。在(zai)公路(lu)施(shi)(shi)工(gong)(gong)(gong)中，應用金(jin)屬(shu)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)代替(ti)(ti)金(jin)屬(shu)筋混(hun)凝(ning)土(tu)(tu)(tu)進行涵(han)(han)洞(dong)(dong)施(shi)(shi)工(gong)(gong)(gong)的(de)歷史已經(jing)有(you)100多年了(le)。1896年，美國(guo)率提高前輩行波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)通道、涵(han)(han)管(guan)(guan)的(de)可行性(xing)研究。其后，在(zai)美國(guo)、加拿大、澳大利亞等(deng)國(guo)的(de)公路(lu)建(jian)設中，均采(cai)用了(le)金(jin)屬(shu)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)進行涵(han)(han)洞(dong)(dong)的(de)施(shi)(shi)工(gong)(gong)(gong)。1990年，日本(ben)高速公路(lu)設計(ji)，規(gui)范制定了(le)波(bo)(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)設計(ji)技(ji)術規(gui)范。 ;
